Description

Base station antenna Technical Field The present invention relates to the field of communications devices, and in particular, to a base station antenna. Background When various large activities are held in remote areas, the on-site passenger flow volume is greatly increased in a short time, the use amount of mobile terminal equipment is synchronously increased, and higher temporary demands are put forward on-site network communication signal coverage and transmission capacity. In order to ensure the unobstructed network signals on site, the mobile base station antenna is transported to the active site by the mobile carrier for temporary signal blind compensation and enhancement so as to meet the communication requirements on site. Currently, a conventional mobile base station antenna mainly comprises a base station main body and a plurality of plate-shaped antennas, wherein the plate-shaped antennas are used as core components for receiving and transmitting signals, and the installation angle of the plate-shaped antennas directly determines the signal coverage range and the transmission quality. The traditional mobile base station antenna has the technical defects that firstly, the angle adjustment of the plate-shaped antenna is manually operated one by workers, the adjustment process is tedious and time-consuming, the deployment of the antenna is difficult to quickly complete on the temporary movable site where workers are stressed, and the timeliness of signal guarantee is affected, secondly, the plurality of plate-shaped antennas after the adjustment are in an unfolding state, the whole occupied space is large, the space cost in the transportation process is increased, the antenna parts are easily damaged due to collision and scratch in the transportation and installation processes, the service life of equipment is reduced, thirdly, the workers are required to manually reset and fold each plate-shaped antenna during the storage, the operation efficiency is low, the safety risk of equipment collision and personnel operation exists during the manual operation process, and the portability and the operation convenience of the equipment are poor. Disclosure of Invention In view of the above, an object of the present application is to provide a base station antenna having a storage function and improved portability. The utility model provides a basic station antenna, including the storage bin, the storage bin swivelling joint has the lead screw, threaded connection has the elevating seat on the lead screw, be provided with limit structure between elevating seat and the storage bin, fixedly connected with a plurality of supports on the elevating seat, all rotate on every support and be connected with plate antenna, the torsional spring is installed to plate antenna and the rotation junction of support, the lead screw upper end is rotated and is connected with the fixed plate, the fixed plate passes through L shaped plate fixed connection in the storage bin, fixedly connected with a plurality of stay ropes on the fixed plate, the other end of a plurality of stay ropes is fixedly connected with at plate antenna upper end respectively.
